Are you looking to add some audio flair to your Arduino projects? Whether you're building a custom alarm system, a game, or just want to experiment with generating different sounds, using a Piezo buzzer with Arduino can open up a world of possibilities. In this guide, we'll explore how to create sound effects using a Piezo buzzer and an Arduino microcontroller.

What You'll Need:

Arduino board (such as Arduino Uno or Arduino Nano)

Piezo buzzer

Jumper wires

Wiring:

Connect one leg of the Piezo buzzer to digital pin 8 on the Arduino.

Connect the other leg of the Piezo buzzer to ground (GND) on the Arduino.

That's it! Your hardware setup is complete.

Code:
Now, let's dive into the code. Below is a simple example to generate a tone using the Piezo buzzer:
